See http://www.john-daly.com/huonpine.htm. His basic complaint is that Cook compared the tree rings to three local temperature series, Launceston, Hobart, and Low Head. All three of these are problematical, Launceston and Hobart have a probably significant but uncorrected UHI, and Low Head has an uncorrected instrumental error that John exposed. The Low Head temperature site has become screened by trees from the prevailing winds over the past decades, andf as a result shows a marked daytime temperature increase. There are many rural stations with that could have been used instead. A further complaint of JD’s was that the trees are on the West side of Tasmania, and all three of the temeprature sites on the East, and Tasmania has a marked East/West climate variation, for example mean annual precipitation is 445 mm on the East, and 3546 mm in the West. Worth further investigation perhaps.
